A-L864 Medium Intensity Red LED Flashing Beacon
The A-L864 Medium Intensity Red LED Flashing Beacon is designed to visibly mark any obstacle that may present hazards to aircraft navigation. It is an economical alternative to incandescent lighting for towers or masts. Rugged construction, low power consumption, RF shielding and long life make this the ideal choice for marking antennas and masts.
The A-L864 utilizes solid construction and a robust power supply to provide multiple levels of shielding and filtering. This makes the unit very resistant to damage from RF fields, lightning hits, or voltage spikes. Austin’s engineering team have used their unique understanding of RF design to build a light that is specifically suited for the most demanding applications.
Austin’s A-L864 has redundant LED elements, so light output is maintained even in the unlikely event of multiple LED failures. It is also compatible with existing load-monitoring fault alarm systems.
The A-L864 features a switchable internal flasher circuit. When the flasher is enabled the beacon may be operated as an independent unit without the need for further accessories. It is also compatible with existing photocell controls.
Benefits Offered by the Austin A-L864 Flashing Beacon
- RF-Hardened design suitable for operation in high-powered MF (medium frequency) to VLF (very low frequency) systems
- Direct replacement for existing incandescent or other light sources
- LED based beacon lasts up to 5 times longer than incandescent lamps
- LED based beacon utilizes up to 90% less power than incandescent lamps
- Constant light output that meets or exceeds regulatory requirements across input voltages ±20% of nominal
- Weather/corrosion resistant beacon assembly and housing
- Integrated flasher assembly allows stand-alone operation of single beacon assembly systems without the need for external controllers
Custom mounting options are available upon request.

A-L810 Steady Burning Red LED Obstruction Light
The A-L810 red LED obstruction light is designed for steady burning use. It can be used to visibly mark any obstacle that may present hazards to aircraft navigation. The A-L810 LED Obstruction Light is an economical alternative to incandescent lighting for towers or masts. Rugged construction, low power consumption and long life make this ideal for structures requiring a Low-Intensity type A or B light. (ICAO Annex 14 Regulations).
The A-L810 utilizes a regulated power supply to maintain consistent photometric output under a wide range of operating conditions. As a result the light is highly resistant to voltage swings, brown-outs, surges and spikes. The unique power supply design also make the A-L810 perfectly suited for applications where intense RF fields may be encountered.
The A-L810 has redundant LED elements, so light output is maintained at required levels, even in the unlikely event of multiple LED failures.
Austin’s A-L810 may be operated as an independent unit, or be installed as part of a complete set of beacons and side-lights. When used with Austin’s A-LCA1 photocell & control panel, the tower operator will receive an alarm signal if a fault occurs in the light or tower wiring. The A-L810 is also compatible with existing photocell controls.
Benefits Offered by the Austin A-L810 Light
- RF-Hardened design suitable for operation in high-powered MF (medium frequency) to VLF (very low frequency) systems
- Direct replacement for existing incandescent or other light sources
- LED based obstruction light lasts up to 5 times longer than older incandescent lamps
- LED based obstruction light utilizes up to 90% less power than older incandescent lamps
- Constant light output that meets or exceeds regulatory requirements across input voltages ±20% of nominal
- Weather/corrosion resistant lamp assembly and housing
- Self contained wiring compartment within base housing eliminates need for additional junction boxes
- Available as either a single or double obstruction light assembly
Universal tower mounting bracket available as an optional extra
Supplied with standard 1” NPT and reducer bushing to 3/4” NPT threaded opening for rigid conduit
Optional universal mounting bracket also available
